T o all whom it may concern:

Be it known that we, Bnm'rio F. Hasn and ALBION L. BUoKNAM, citizens oit the United States, residingat lashing-ton, in the District oiE Columhia, have invented certain new and useful improvements in De vices for Preventing the Retilling of Bottles,

of which the following is a description, relierence being had to the accompairying,- drawplace ot' what has heen poured out, that is,`

, will make the introduction of liquidv so diiiicult as to render n0n-reillable.

the receptacle practically lith this object in View, our invention vertical sectional View of the'neck of a bottle having the device of our present invention in place therein. Fig. 2 is a perspective view of the valve protector. Fig. 3 is a perspective view of the ball. Fig. l is a peri spective view of the inner valve seat ring, and Fig. 5 is a perspective view of the outer valve seat ring.

In the drawings, l represents a bottle having neck 2, here shown as provided with a shoulder 3, which is not, however, essential and may be dispensed with.

4 vis the outer valve seat ring secured .in the neck of the bottle resting on the shoulder 3 if the neck is provided with this shoulder. This ring comprises a cylindrical portion 4; and a Hat end portion 42 having a central orifice 5.

6 is the inner valve seat ring having central orifice 7 and valve seat 8 adapted to receive the ball 9 hereinafter explained. The exterior diameter of the inner valve seat ring 6 is less than the inner diameter ot the cylmdrical portion 4 of the outer valve seat ring, so that it will be movable from side to side, the thickness of the ring, that is, they.

dilerence between its otfter and inner dil nineter, lacing proportioned 'to the diamel ter ot the ori ce 5 that it will always be in contact with Ythe upper tace of the end portion at?, tor at least a portion of its width completely around the oriiice 5. The height oit the ring; t3 the same as, or .less than the reicht of the inner :tace of the cylindrical portion al ot the outer ring.

)there or outside of the rings L and 6 is a valve protector 10 having a. central frustoconical recess l'l extending up into it of suliieient diameter to permit'the ball 9 to move freely therein. The walls of the recess ill are slightly thicker at their lower ends than the thickness or' the cylindrical portion 4l ot the rinvj Llso as to extendv inward sutilciently to hold the ring 6 within the ringfl.

The valve protector l() is provided on its exterior about midway between its ends with an annular groove 10. the groove l2 is provided with longitudinal rooves 13, and the portion below the groove 12 is provided with longitudinal grooves la which communicate 'at their lower ends by passages l5 with the recess l1.' The grooves t3 and lt are so located that no groove 13 will be in line with any groove 14. The grooves i3 and lll: are here shown as three in number, hut a larger or less number may be used. and the number of grooves i3 may ce the same as or less or greater than the ninnlgier of grooves 11i, provided always that no groove in the upper portion of the yalve protector is in line with a groove in the lower portion.

rilhe ring a and the valve' protector are in tended to fit stmgly within the neck of the bottle and are to he secured therein, preferably by cement such as water glass cenient. of porcelain or glass, though one or more ot ,them may bernade of metal.

After the bottle has been illed with liquid 'the ring fl is placed and cemented in position; the ring,r G is then placed in p0- sition; then the ball and last,the valve protector is placed and cemented in position. Or, it preferred, the parte may be assembled outside the bottle neck, the' ring' 4- and the valve'irirotector being preferably cemented togethe at. their ends, and the device introduced as a whole into the neck 0f the filled hottie.

ln order lo pour out the contents of the bottle, it f .ust tipped so that the neck The portion above eeeeefi will point downa'ard at alieni an ngie ei 450 le the horizontal 7Wnen se il); ed, the
